Tests confirm up to 27% fuel savings on ships from Onboard DC Grid

ABB, the leading power and automation technology group, today released third-party verification that its Onboard DC Grid helps vessels reduce their fuel consumption, cut noise and trim their environmental impact.

The measurements and tests, conducted by Pon Power in collaboration with ABB on Myklebusthaug Offshore’s platform supply vessel “Dina Star,” identified reduction of specific fuel oil consumption of up to 27%. These are the first documented results from a vessel outfitted with ABB’s OnboardDC Grid, which allows engines to run at variable speeds for top fuel efficiency at each load level.

“Our Onboard DC Grid is a significant step forward for electric propulsion. We are pleased that the concept delivered results that exceed our expectations”, said Veli-Matti Reinikkala, head of ABB’s Process Automation division. “Onboard DC Grid is a competitive advantage to ship owners operating a wide range of ship types from offshore vessels to ferries and yachts seeking to increase fuel efficiency and reduce emissions.”

"Noise and vibration reduction has already been a focus of ours for years with our GenFlex Design solution. The ability now to document this level of fuel efficiency alongside the noise reduction is a very important new step for us as a power solution provider, especially for our customers operating in challenging conditions", says Ole Knarberg, Commercial Director for the Marine segment in Pon Power Scandinavia. Dina Star is powered by four Caterpillar 3516 engines in combination with a C32 in a variable speed application.

“We operate in a highly competitive market where customers are increasing their focus on operational costs and environmental impact. The results from Dina Star, the first vessel to feature ABB’s advanced Onboard DC Grid technology, are promising and enhance our competitive edge”, says Tore Myklebusthaug, General Manager at Myklebusthaug Management. “Based on the test results, we can now confidently say that the Onboard DC Grid delivers considerable fuel savings, to the benefit of the vessel charterers.”

ABB introduced the innovative Onboard DC Grid power distribution system in 2011. Platform support vessel “Dina Star,” delivered to Myklebusthaug Management by Kleven Yard in 2013, is the first vessel powered by the Onboard DC Grid. ABB’s Onboard DC Grid power distribution system was granted “Approval in Principle by American Bureau of Shipping” in January 2014.
